The demand for health care has increased with the development of global technology and the rise of public health awareness, and smart service systems have also been introduced to medical care to relieve the pressure on hospital staff. However, the su

Nonlinear Optics (NLO).
To explore resonance phenomena in the nonlinear region, we show by experimental measurements and theoretical analyses that resonance happens in modulation instability (MI) from non-instantaneous nonlinearities in photorefractive crystals. With a temp

We design an interferometric method for measuring the fractional orbital angular momentum of a vortex light beam by cascading Mach–Zehnder interferometers. The validity of this method is verified by simulation and theoretical analysis. We demonstra

We find theoretically that the optical modulation instability can spontaneously happen in the noninstantaneous defocusing medium when there is a coherent feedback. It requires both above-threshold gain and phase matching for the instability to happen

We report the experimental observation of the dynamic pattern formation of a broad coherent light beam in a biased photorefractive crystal due to the spatiotemporal modulation instability. When the nonlinearity exceeds a specific threshold, the coher

We have measured and simulated the dynamic evolution of a soliton beam that is launched into a biased photorefractive crystal with a sinusoidally oscillating incident position. Within some frequency range depending on the optical intensity, the swing

With measured optical images in spontaneous pattern formations, we observe the phase boundaries in the phase diagram, defining by the degree of coherence and biased voltage. Pattern transitions in the form of stripes, reoriented stripes, hexagons, an

While a fundamental Gaussian light beam can form stably a spatial soliton in certain self-focusing medium, a single-wave topologically integer-n-charge vortex light beam cannot. It breaks up into 2n filaments due to symmetry breaking and azimuthal in
